ECONOMIZER AND Dacha-acumen roe rmam-Aezeolvrg gs x q fi s j Beit'know-n'that I GEORGE LLEWELIJYN DnN'roN JAMES, a-subject ofHisMa-jesty the" King of Great-Britain, residing at 17 Epsom Avenue,Epsom, Auckland, New Zealand, have invented a certain new and use- 7 fulImprovement in an Economizer and. Be-

carbonizer for Internal-Combustion Engines, of which thefol'lowing is aspecifi cation.

This inventionrelates to internal combustion engines and provides fortheutilization ofthe heat and gases contained in the exing power areconsiderably:enriched and {of an englne,

. greater "power is obtained. 1; i

According tov the inveition I'wa'ter -isvapourlsed by the heat of theexhaust pipe rected into a steam in the upper portionof said 'casing. e.

The bottom of the leeve valve has a central port therein and forms thetop steam jacket, andcloses on a seating around the outlet ofsaideentral passage, while a needle valve adjustably secured through thetopoif the sleeve valve closes saidp'assage.

Thesleeve valve is provided witha raised thread which screws into thecasingaa'nd is the casing to the engine-fuel intake also provided withan elongated port opening through its circumference, andgadapt'ed toibe.brought opposite a gas connection from A control leer adjustablysecuredt o the top of said sleeve valve'enables same toloe j partially turnedand raised bythe one operation, so as to open the'stea-m jacket and thecentral passage, to the interior of the's'l'ee've valve,simultaneouslywith the putting of the latter into communication'with thegas connection to the engine intake, through the aforesaid elongatedport.

Provision is made for regulating the pas sage of Water to thevapouriser, and the desired amount of air can also be admitted to V thesteam jacket by providing air, exhaust gases, 1 and:

the steam produced being diacket in the lowerifend' of a casing, andsurrounding a central pas; sage from the engine exhaust pipe'to 'asleevevalve which servesas a gas generator of the Specification of LettersPatent. I i. '7 Patefd 3,11: 7 Application filed November 19, isle.sea-a1:uufa'eaaai.

The casing 7 is screwed into the exhaust pipe 4 by means of a nipple 7the passage 8 passing through the latter/and, leading from the pipe'e toa sleeve valve 10 located in the upper portion ofsaid casing 7. f

' The passage 8 terminates at itsup' re d and surrounding in a iet9,-and entree screwing on the}? nipple locks the'casi'ii'g 7 on the pipe4. I 'I The passagefo has an air inlet at 111, and" is provided with anair admission valve 12 by meansof which the desired amount of air can beadmittedto mirwit-hthe steam m i g o the jacket '6, i

From the u er rti n of the eain r, a

connection 13 leads to, the 'fueLiiitake of the engine and enters sameafter-the ordinary.- carburetor or vapouriser connect-ion, thin teriorof thevalve-1'0 being-openedto-the connection 13 through a port- 14opening the latter being-given a part ialtiirn-.f

The valve or gas-generator ,1'0 i'sclosdat through the circumference orthe valv on i its upper end'aiid'has ae'entral opening 15 in its "lowerend,th=e eegeer said eipemag 1'5 closing-on recessed-seating .15? surrounding thejetetr-thepassage 8i When the valve-or gasjflgerrerater l'ois "raised se' that the edge of the opening 1 51l 1 ft S Off therecessed seating 15*, the stea'ifijaek't cue" put into communicationwith the interior v j of the valve 10. V e

" A needle valve'16 capable ofadjustment through the upper end of'thevalve 10, by

having an upper screwed end andqa cross ,16-adjusted in the valve 10,the latter and the valve 16 and rlever 18 are locked together by the nut'21 screwing on the valve 16.

A raised or projecting. thread 22 around the upper end of thesleevevalve and working in a corresponding thread cut in the casing 7, enablesthe sleeve valve 10 and needle'valve 16 to be raised together toopen thesteam jacket 6 and the passage 8' to the interior of-the valve 10,simultaneously with the bringing of .the port 1% opposite the connection13, by the one and same partial turning movement of the control lever18, whereby gas generated in the sleeve valve 10 is permitted to pass tothe engine intake. 7 A stop 28 screwed through the casing 7 and enteringthe port'ld limitsthe turning movement of thesleevevalve 10 in eitherdirection. V

The port 14 is tapered at its end which is first brought opposite theconnection 13, in order that the amount of gas passing from the interiorof the valve 10 to the connection 13 may be regulated to a small degree.

The valves 2, 10 and 16 all being capableof independent adjustment theproportion a of air, exhaust gas and steam delivered to the combustionchambers of the engine cylinders is adjustable in accordance with thevalue of the liquid fuel vapor, thereby enabling the obtaining of themost efficient mixture of gases.

The mixture produced not only enables more power to be produced whenmixed with kerosene and benzine hydrocarbons, but thecheinical effect issuch that carbon is consumed. c I

The admissionof air prolongs the period of explosion giving less violentmomen tary impulse, thereby eliminating the objection tothe use ofhydrogen in internal combustionengines.

As the connection 13 from the device communicates with the intake of theengine after the carburetor or vaporizer, the gas produced by myinvention mixes with the fuel vapor orgases and proportionatelyreducesfthe evaporation ofliquid fuel in such type of engine.

What I do claim and desire to secure by Letters Patentof the UnitedStates is 1. An attachment to internal combustion engines, comprising, acasing in communication with the fuel intake of an engine and having apassage through its lower end communicating with the exhaust pipe of anengine; a steam jacket surrounding said passage and in communicationwith a vaporizer;a gas mixer in said casing above said jacket, adaptedto receive steam and engine'exhaust gases; and means for controlling theentrance of steam and engine exhaust gases to. said mixer and the exittherefrom of gas mixed, for the purpose set forth, substantially asdescribed.

2.. An attachment to internal combustion engines,.comprising, a casingin communica-' tion with the fuel intake of an engine, and having apassage through its lower end communicating with the exhaust pipe of an,

I engine; a steam. jacket surrounding said passage; a vaporizerconnected to said steam jacket; an air inlet in the connection betweensaid vaporizer and said jacket; a gas mixer in. said casing above saidjacket and adapted to receive steam, air and engine ex haust gases; andmeans for controlling the entrance of steam and engine exhaustgasestosaid mixer and the exit therefrom of gas and steam, for the purposeset forth, substantially as described.
